!!!! Only experiment with shortcutting capacitor if you know how to handle !!!!
This setup is only 10µF charged to 60V and I use leather gloves.
Creating shortcut on same capacitor with higher voltage can be really dangerous.
There can be a lot of energy stored inside a capacitor eventhough it's for example 10µF but charged to 400V.

When we shortcut a charged capacitor that is connected to one side with Earth ground, we see current flowing in the Earth ground connection.
This picture shows you the results on low voltage setup:

That was done by manually switching.

What helped to get bigger currents was also a plate on the capacitor:

Creating the shortcut with thick copper bar also helped.
